*1 Although the accounting period of RY2015 is nine months (April 2015 to December 2015) due to the change of the account closing time, the period for the environmental data is set to be a year.
Consolidated net sales used to calculate the environmental load per unit of consolidated net sales (CO2 emissions, energy use, CO2 emissions during distribution, amount of waste discharged, water consumption, VOC emissions, amount of PRTR-designated substances released and transferred) for RY 2015 are the total consolidated sales from April 2015 to March 2016.

*2 Of the overseas consolidated subsidiaries, for Great Plains Manufacturing, Inc. (GP), which became a consolidated subsidiary in July 2016, the period of its environmental data is six months (July 2016 to December 2016), and the data except for its four major production sites (account for over 80% of sales of GP Group in RY2016) and four major non-production sites (accounting for over 90% of the employees of non-production sites of GP Group in RY2015) is estimated.
Data of the amount of chemical substances (VOC) handled and VOC emissions are excluded from the calculation.

*3 The coverage of consolidated subsidiaries is 100% for each year.

*4 Starting from RY2014, part of the affiliated companies accounted for under the equity method are covered by the data.

[RY2011 to RY2015]<Fuel>Based on the Manual for Calculation and Report of Greenhouse Gas Emissions (Japan's Ministry of the Environment and Ministry of Economy, Trade and Industry)

<Electricity>Data for Japan are effective emission coefficients for each electricity utility, and overseas data are according to the GHG emissions from purchased electricity (GHG Protocol).

[RY2016]<Fuel>Based on the Manual for Calculation and Report of Greenhouse Gas Emissions (Japan's Ministry of the Environment and Ministry of Economy, Trade and Industry)

<Electricity>Data for Japan are effective emission coefficients for each electricity utility, and overseas data are according to CO2 Emissions from Fuel Combustion - 2016 edition (IEA) and The Emissions & Generation Resource Integrated Database (eGRID) (EPA).

The method for calculating non-energy source greenhouse gas emissions is based on the Manual for Calculation and Report of Greenhouse Gas Emissions (by Japan's Ministry of the Environment and Ministry of Economy, Trade and Industry)

The amount of CO2 emissions in RY1990 is solely the amount of CO2 emissions from energy sources at Kubota production sites.

Calculation method is from the Manual to Support Merchants regarding Revisions to Energy Conservation Laws , 3rd Edition (April 2006, Japan's Energy Conservation Center of the Agency of Natural Resources and Energy, Japanese Ministry of Economy, Trade and Industry)

CO2 emissions during distribution (kilotons CO2e)

CO2 emissions during distribution = Σ [Fuel consumption for freight shipment by truck × CO2 emission per ton-kilometer by fuel of transportation] + Σ [Fuel consumption for freight shipment by rail and water × CO2 emission per ton-kilometer by means of transportation]

Calculation method is based on the ton-kilometer method stipulated in the Manual for Calculation and Report of Greenhouse gas Emission (Japan's Ministry of the Environment and Ministry of Economy, Trade and Industry)

The calculation method is based on the Basic Guidelines regarding the Calculation of Greenhouse Gas Emissions throughout the Supply Chain (Japan's Ministry of the Environment and Ministry of Economy, Trade and Industry) and the Emissions per Unit Database for the Purpose of Calculating the Greenhouse Gas and Other Emissions of Organizations throughout the Supply Chain

Transportation expenses paid by method of transport are for airline tickets and railway tickets

For a part of the overseas subsidiaries (68 sites), estimate by multiplying the net sales of the subsidiaries in each of the regions and countries mentioned by the ratio of transportation expenses for each method of travel included in the net sales of major subsidiaries in Europe, America, Asia and China.

CO2 emissions per unit: Fuel consumption per hour × Annual hours of use × Years of service life × per-unit heat value of each fuel × CO2 emission coefficient of each fuel (calculated by assuming the fuel consumption per hour, annual hours of use, and years of service life for each product)

Chemical substance-related

Indicator (unit)

Calculation method

Amount of PRTR-designated substances handled (tons)

Total amount of chemical substances handled at Japanese sites, which are designated as Class I under the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (the PRTR Law) whose amount handled by each business site is one ton or more (or 0.5 ton or more for Specific Class I Designated Chemical Substances) per year

Amount of PRTR-designated substances released
and transferred (tons)

Total release and transfer amount of the chemical substances which are designated as Class I under the PRTR Law at Japanese sites and whose annual total amount handled by each business site is one ton or more (or 0.5 ton or more in case of Specific Class I Designated Chemical Substances).

Amount released = amount discharged to the atmosphere + amount discharged to public water areas + amount discharged to soil + amount disposed of by landfill in the premises of the business site

Amount transferred = amount discharged to sewerage + amount transferred out of the business site as waste

The amount of each substance released and transferred is calculated in accordance with Manual for PRTR Release Estimation Methods Ver. 4.1 (March 2011) of the Japan's Ministry of the Environment and the Ministry of Economy, Trade and Industry, and Manual for PRTR Release Estimation Methods in the Steel Industry Ver. 13 (March 2014) of the Japan Iron and Steel Federation.

Amount of chemical substances (VOC) handled (tons)

Total amount handled at overseas sites of the six substances of xylene; toluene; ethylbenzene; styrene; 1, 2, 4-trimethylbenzene; 1, 3, 5-trimethylbenzene that are at each site handled in amounts of one ton or more per year

VOC emissions (tons)

The total emissions of the six substances of xylene; toluene; ethylbenzene; styrene; 1, 2, 4-trimethylbenzene; 1, 3, 5-trimethylbenzene that are at each site handled in amounts of one ton or more per year
